当我应用黑色背景颜色时,我不明白为什么在自举4旋转木马顶部会出现意外的白色背景。我该如何纠正这个意想不到的问题?您可以在此处找到此问题的示例https://codepen.io/edquijano/pen/MQxogR感谢您的意见。

   <div class="carousel">
    <div class="bg-dark">
    <div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
        <ol class="carousel-indicators">
            <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
            <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
            <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
        </ol>
        <div class="carousel-inner">

旋转木马被封装在overlay div中,其不透明度为0.6。这使得图像看起来像是在他们身上发白 您可以选择删除图片上的overlay div或explicity set opacity:1
以下是移除了overlay div的输出:https://codepen.io/anon/pen/XZGevv
